      Review & Installation Video

      I’m Justin from, and this is our handling bolt-on build-up for all ’99-‘04 Mustang GTs. The goal with this build is pretty simple, we’re looking to take some basic suspension components, install them on our 2000 GT here, in an effort to make it handle a lot better than it does now in stock form. Now, individually, installed each of these parts will make a slight difference in your car’s handling. However, when installed together, like we’re going to do today, they should make a substantial difference in our cars’ handling and should make our GT handle like it’s on rails. First up on the list to install is this black strut tower brace that we have laid into place, just so we can see how it’s going to sit. Now this is a very popular first step for making your car handle a little bit better, and it’s going to be pretty easy on your wallet as well. Now basically, this is going to firm up the front end and reduce chassis flex and body roll. I have to admit, that black powder coated finish is going to look pretty cool under the hood as well. The next mod we’re going to go with for our handling pack is a set of these QA1 Caster Camber Plates. These are going to be very valuable for getting our GT’s alignment back in spec after we lower the car. A properly set up alignment will not only help your cars handling, but it’s also going to save your tires from premature wear. Speaking of lowering the car, what suspension build would be complete without a set of lowering springs. We’re going to install a set of these SR Performance lowering springs which will lower our GT roughly an inch and a half or so on all four corners. Not only will this help our ride handle a lot better thanks to that lower center of gravity, but it’s also going to help our appearance as well by getting rid of that ugly wheel gap. Last and certainly not least are these front and rear sway bars from Eibach, sway bars are one of the biggest factors to reduce body roll and are a great tool for fine tuning your suspension. From the factory most Mustangs have the tendency to plow or push through turns, this is referred to as under steer. By installing a larger rear sway bar and tweaking the front, you’re actually going to eliminate that under steer and introduce a little bit of over steer, which means the rear of the car is going to come through the turns much quicker, and actually make the car a little bit more fun to drive. So those are the parts we have in store for our GT here today, now let’s get everything installed so I can get our GT out of the ‘shop and onto the streets, and see the difference this handling pack makes. Alright so I just got our 2000 GT out of the ‘shop and onto the street here, and it took me all of 5 seconds the realize what a difference this handling pack makes to our ride. Gone is the kind of floaty, disconnected feeling that our Mustang used to have, and it actually now feels like a sports car, it feels like it should - much more firm, much more planted, even going straight, obviously through the turns it’s a lot better as well. The car just feels like it wants to respond to your actions a lot more, making it feel like you’re actually part of the car, which is great, and you can just slide turn to turn, going straight here like I said, the car just reacts well to whatever you want to do to it. We have a nice right hander coming up, let’s see how the car reacts with our new mods installed. All right, so much better, the car is just so firm and so planted going through those turns, that can definitely be attributed to those sway bars working with that SR Performance strut tower brace to really reduce our body roll and our chassis flex. I got a nice left hander coming up as well. Oh yeah, you can totally come into a turn now with much more speed and much more confidence going through the turns. The nice thing about the springs too, obviously they lower the car making it look a lot better and handle a lot better, but it’s also better for acceleration and our braking. The car doesn’t want to nose down now when you’re hard on the brakes coming into a turn, making it feel a lot more solid. Those QA1 Caster Camber plates are probably not going to make the biggest difference in your everyday drive however it was able to get our car back into spec after we lowered it about an inch and a half, just so we didn’t chew up our tires and made for a lot better handling. So there you have it, this handling pack really made a world of difference on our GT and really made our car a lot more fun to drive. Be sure to check out some of our other ’99-’04 bolt-on build ups where we work on our appearance, help get our GT off the line, and give it some more power.

        Better than Stock

        I am not sure about the exact improvement on cornering ( I installed Maximum MotorSports Panhardbar, Lower Control Arms, and Torque arm along with many other suspension components at the same time. One thing is for sure . . . car handles much better. It's like day and Night. I am sure Eibach Anti-Roll Sway Bars complement all the other suspension parts.

        I can honestly feel the difference when i corner when i added these to my gt. BUT i also added supporting mods before this. I have a strut tower and body braces welded on with all this the car handles perfectly.

      Different size dimensions from stock? My stock rear sway bar clanks against my magnaflow catback when I go over large bumps. Does this sway bar differ in size? I'm trying to fix the issue. It's rubbing against the sway bar after the rear axel, but only makes contact when I hit bumps in the road.

      • All I can say is that the Eibach sway bars are quite a bit beefier than stock and do improve stability (especially the front bar. I'm glad I bought the set. I cannot say whether or not they'd clear your exhaust system because the bars installed exactly in the same manner as the stocks. This seems to be an apples and oranges issue in that I believe you have a problem aside from the bars. My suggestion would be for you to re-route or re-clamp your catback in such a manner that eliminates contact. Concentrate on improving the exhaust install. Hope this helps or gives you something to think about to solve your problem.

      Do these sway bars help make the car more neutral? (Reduce Understeer) I road race my 02 GT, and right now, even after putting 2 degrees neg camber and h&r race springs, the thing still has understeer up the yin yang. I know that a lot of this is because the rear sway bar a rather "soft" sway bar. So, now my question, does this sway bar kit make the car more neutral during turn in and throughout the corner? Thanks a million!

      • Yes, these will help make the car more "neutral" by reducing body roll in the corners, but if you're even a little serious about racing I'd suggest doing more than just sway bars. Most suspension parts are relatively cheap and easy to install. I'd consider going down the list of usual suspects starting with rear upper and lower control arms and MM subframe connectors. They'll both help flatten you out in the corners fairly dramatically for about 500 all together. Hope this helps.
